electricpy.fault.short_circuit_mva(Zth=None, Isc=None, Vth=1)[source]¶

Short-Circuit MVA Calculator.

Function defines a method of interpretively calculating the short-circuit MVA value given two of the three arguments. The formulas are all based around the following:

\[MVA_{sc} = V_{th}*I_{sc}\]

\[V_{th} = I_{sc}*Z_{th}\]

Parameters:¶

Zth : float¶

The Thevenin-Equivalent-Impedance

Isc : float, optional¶

Short-Circuit-Current, if left as None, will force function to use default setting for Vth. default=None

Vth : float, optional¶

The Thevenin-Equivalent-Voltage, defaults to a 1-per-unit value. default=1

Returns:¶

MVA – Short-Circuit MVA, not described as three-phase or otherwise, such determination is dependent upon inputs.

Return type:¶

float
